Ok... I finally figured out what the problem is. When I save my OC profile it sets the C1E and Vcore to AUTO. The only way to fix it is to clear the BIOS (jumper). I tried clearing the BIOS before, but I loaded a saved OC profile right after, so it didn't work. Not sure why just saving a OC profile will do this, hmmm!
Even though I'm able to set the Vcore I can't get the board to go beyond 9x340MHz with a Q6600 CPU. I've went as high as 1.6V with all other voltages maxed, but it's a no go 

 I have another identical CPU to this on a P35 board and it overclocks to 3.4GHz on air, so it's not the CPU.
Time to retire this mobo I guess.
